Atmospherical pressure filling machine capable of preventing dropping liquid from being sucked back

Abstract

The invention discloses an atmospherical pressure filling machine capable of preventing dropping liquid from being sucked back. The atmospherical pressure filling machine structurally comprises a feeding hopper, a fixing seat, a fixing frame, a worktable, a filling head and a connection cavity; the feeding hopper is mounted on the fixing seat and communicates with the connection cavity; the filling head is arranged at the bottom of the connection cavity and arranged in the due north direction of the worktable, the filling head and the worktable are matched, and the fixing frame and the fixingseat are mechanically welded; and the fixing frame is fixedly connected with the worktable. The atmospherical pressure filling machine has the beneficial effects that a flow guiding block is arrangedin a middle cavity, and thus the liquid reaching the flow guiding block is guided under the effects of a guiding plate and a guiding block to achieve the effect of preventing the filling liquid from being retained; a rotating plate drives a telescopic plate to move along with the rotating plate when rotating along the center axis to achieve opening-closing control over an air vent; and with the help of the air vent, air pressure balance of the middle cavity and the outside can be achieved when filling is stopped, and thus the purpose of preventing backflow and suck-back of the liquid due to the fact that the air pressure in a filling pipe is smaller than the air pressure outside the pipe is achieved.

Description

technical field [0001] The invention relates to the field of filling machines, in particular to an atmospheric filling machine capable of preventing dripping and sucking back. Background technique [0002] The liquid is independently powdered in the bottle and sold after sealing it, while the traditional packaging method is to insert the conical funnel into the bottle mouth to guide the liquid into the bottle. Loading machine, the current normal pressure filling machine has the following defects: [0003] After the existing normal pressure filling machine stops filling, because there is no liquid in the filling tube to continue to output, there is a section of empty tube, and at this time, there is still some liquid left in the port of the filling tube. Into the filling bottle, so that the air pressure inside the filling tube is lower than the air pressure outside the tube, so that the liquid at the port flows inward, forming a suck-back phenomenon.
